http://www.top500.org/stats/list/32/os should give you some idea of what the
big`ins are using. Well at least outside the 77% that simply say they are
using "Linux". Seems that about 5% were using CNK/SLES 9 as of the last
list.

Thanks Jan! No point at all! :) I don't mean in any way to belittle
ScientificLinux or any other distros. I have no axe to grind! [I haven't
even used SciLinux much; I did hate ComputeNodeLinux because it did not
allow for dynamic linking (out of the box) which made life a nightmare with
my Python applications! Correct me if I am wrong; CNL users; I am not
disputing that this might have a reason but it was just a feature I did not
need.]
Just making the point that CentOS (IMHO) is as good or bad a choice and I
wish the vendor's let me peacefully live with it! :) To each his own Distro
(within reasonable bounds).
A minor point (very subjective, of course) that makes me prefer one distro
over another is the user-base size.How big is the usage of ScientificLinux,
vs CentOS vs RHEL vs ComputeNodeLinux? I tried to get figures but I don't
have good numbers. {note I left Fedora out since many users reported that it
may not be the most stable one and typical Fedora users might be of a
different profile that what matches a Beowulf application}
In general it is my naive opinion that the number of users of an project in
the *Open Source Community* is well correlated with its "bug-freeness" and
ease of obtaining help from fellow users. Of course, I do pay the penalty of
not having a customized kernel and the attendant performance hits (maybe).
Just a personal choice I guess.
